Sub Defensive Warfare

Abstract

The Submarine Acoustic Warfare (SAWS) Development Program develops acoustic countermeasures, submarine defense capabilities, external launch systems and all acoustic augmentation systems for the U.S. Navy submarines. In FY21 SubTDS begins development testing of ADC MK5 EDM-1 variants. The SAWS Development Program is comprised of the Submarine Defensive Warfare Program, which improves the survivability of all U.S. Submarines. SubTDS The ADC MK 5 acoustic countermeasure (ACAT III) developmental contract awarded in Sep 2018 and is currently in the Engineering and Manufacturing Development (E&MD) phase. The first development (Increment 1) effort of addressing the overall SubTDS program is focused on delivering full internal countermeasure launcher (ICL) functionality providing the Acoustic Device Countermeasure (ADC) MK5 capability to all submarines in the fleet. The ADC MK5 development will result in delivering fully functional test units and Engineering Development Model (EDM) variants. The ADC MK5 will bring new technologies including adaptability packaged in a three-inch diameter body. FY20 funding will primarily support on-going SubTDS development including component and subsystem design, in support of the ADC MK5 Preliminary Design Review. FY21 funding will provide for completion of the Critical Design Review and procurement of multiple ADC MK5 EDM countermeasure variants, which includes four (4) Countermeasure Control Tools (CCT), four (4) STU-E's, (4) STU-A's, and seventeen (17) EDM-1 devices that are recoverable, rechargeable, and reusable. FY21 will also include in water developmental testing at test facilities, test lakes and at sea from US Navy surface ships. Additionally, EDM-2 development and prototyping will begin for maturing the technologies and improve the capability, in preparation of FY22 deliveries. The next development (Increment 2) effort for addressing the overall SubTDS program will begin in FY24 and focus on the development of the External Countermeasure Launcher (ECL) 6-inch acoustic countermeasure, Tactical Decision Aid, and integration of communication interfaces with ship systems for enabling improved adaptive capabilities. FY 2021 funding for SubTDS will continue the development, mature the capability, and deliver multiple Engineering Development Models for supporting contractor and government testing. The Undersea Defense Working Group (UDWG) is a working group comprised of fleet, resource sponsor, (testing community) and acquisition community representatives to assess fleet threats and the effectiveness of our countermeasure and systems against these threats, both known and projected. This includes associated studies, demonstrations, models, and simulations. The Technical Direction Agent (TDA) and In-Service Engineering Agent (ISEA) will provide hardware and software development support for Acoustic Devices Countermeasure (ADC) as well as Countermeasures Set, Acoustic (CSA) systems, future variants, and Acoustic Augmentation Support Systems (AASS) in the Acoustic Augmentation Support Program (AASP), and advanced communication systems improvements in support of the AASP, including component level technical insertion.
